Parameters
- boundingBox
- Type: Ptv.XServer.Controls.Map.Tools.ReprojectionIBoundingBox
Bounding box to transform. - sourceCrs
- Type: SystemString
The source CRS. - targetCrs
- Type: SystemString
The target CRS. - nSupportingPoints
- Type: SystemInt32
Number of supporting points to use. - resizeFactor
- Type: SystemDouble
An additional factor for resizing the resulting bounding box; <0 for adding an offset based on side line deviations, >0 for simply resizing the resulting box.
Return Value
Type:
MapRectangleThe transformed bounding box.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type
IBoundingBox. When you use instance method syntax to call this method, omit the first parameter. For more information, see
Extension Methods (Visual Basic) or
Extension Methods (C# Programming Guide).
Remarks This is extension does not only transform the corner points of a given bounding box but takes into
account that the bounds may be distorted when being transformed to another CRS.
